Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Unedited at normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

#Indonesia #sailingadventure #wonderfulindonesia #liveaboard #sailing #RajaAmpat #Komodo #Flores #SpiceIslands #snorkeling #familyvacation #summertrip Behold the beautiful world of the Mastigias papua ✨Did you know? These jellies have been isolated in rare saltwater lakes and lost their sting due to the absence of predators! We call them farmers because they farm zooxanthellae (tiny marine animals) that turn sunlight into food. They obtain about 70% of their food from the sun and the remainder using very specialized, weak harpoon cells along their graceful, flowing arms. But there's no need to worry; the little harpoons that catch small, unsuspecting swimming animals are too weak to break our skin. Actually, you can't even feel them! Would you join us and swim with them? 🪼 https://hubs.li/Q039lxgW0 👍 If you found this video interesting, don't forget to LIKE and SUBSCRIBE for more adventure in Indonesia through Indonesian eyes!
